PCP Regulator Failure

That's just the explanation I needed. Thank you. I wasn't considering the interactions of the springs with the pressure in the reservoir.

So even if seals are fine, a damaged valve seat will still not seal properly leading to a non-regulating regulator.

I was struggling to get my head around the initial low power section of there curve.

Thanks all.

Yes, the reg will "creep" up to reservoir pressure.
